PEDESTAL PAD Application filed March 29, 1930. Serial No. y440,146.

My invention relates to improvements in pads or feet for the pedestalsof typewrlter or calculating machine stands, or the legs of typewritersor other machines or articles.

The principal object of my invention is to provide an improvedcushioning pad or foot for absorbing shock and noise when used inconnection with a typewriter or other percussive machines and positivelypreventing the machine, or other article to which it is applied, fromslipping along a highly polished floor or desk as the case may be.

Another important object is to provide a pad or :toot which is welladapted for long use, that is to say Jfor retaining its cushioning,

silencing, and non-slip characteristics.

Other objects-are the production of a device ot this character which maybe attached to machine legs or pedestals of different sizes, is simplein construction, and inexpensive to manufacture.

Other and subordinate objects will appear and the nature of myimprovements will become apparent as the succeeding description isdeveloped.

In the accompanying drawing there has been illustrated a preferredembodiment of my invention:

Figure 1 is a view in side elevation illustrating my improved pad orfoot applied to one leg ot a typewriter pedestal or stand,

i `igure 2 is a top plan View,

Figure 3 is a transverse sectional view taken on the line 8-8 of Figure2, and

Figure 4 is a similar view taken on the line 4.--4 of Figure 2.

Referring to the drawing by numeral, 1 designates one of the legs of apedestal, not shown, such as is used as a base for typewritingorcalculating machines, and 2 my novel pad or foot applied thereto.

The pad or foot, in the form illustrated, includes a socket member 3,preferably construct/ed ot a suitable metal, and having an in- 45 vertedcup shaped form to provide a depending ange or skirt 4 and a chamber 5.The top 6 of the socket member, which is preferably Hat, is providedwith upstanding lugs or prongs 7, in this instance four in number, theaxis of the disposed concentrically ot socket. The lug or prong 7 may beformed integrally with the top 6 by stamping them ont along radial linesand bending them up, or in any other suitable manner. It iscontemplated, however, that the lugs 7 shall be adapted to be sprung,outwardly, from an inclined position as shown in dotted lines in Figure8, to yieldingly grip the legs 1 and be adaptable to tit legs ofdifferent sizes. To this end the material of the socket 3 may besufficiently resilient to impart to the lugs 7 the character described,when they are formed integrally therewith, or the lugs only may beformed of resilient material and attached in any suitable manner.

A cushioning member 8, of disc-like form, littin g snugly within thechamber 5 and projecting for a suitable distance below the skirt 4, issecured to the socket member 2 as presently described. The cushioningmember is preferably formed of sponge rubber, or a similarly resilientpliable material which will not harden under long use.

Said cushioning member 8 is provided in its lower portion with bore 9extending for a suitable distance from its bottom to form a vacuumchamber. smaller counterbore 10 is provided in the upper portion o f thecushioning member. single rivet 11, passing through an axially disposedrivet opening 12 in the socket member 3, and said counterbore" 10,clamps the cushioning member 8 between the upper surface of thechamber 5and a retaining plate 18 seating against the upper end wall of the bore9.

In operation, the skirt of the socket member keeps the pliable spongerubber cushionan axially disposed` ing member 8 from spreading While atthe same time because of its pliable nature and the bore 9 itacts as avacuum cup and prevents creeping. The socket member 3 can be drawn froma single piece of material such as steel and the cushioning member 8inexpensively produced as by molding so that the entire device can becheaply manufactured.

What I claim is:

A pedestal foot or pad including, a circular socket comprising a bodyportion having 2 momen i a down turned marginal `flange and a series ofnpstandinpT prongs struck up radially from the body portion to receivethe pedesta] therebetween and to provide a central hub portion, saidsocket beingr formed from a single piece of sheet metal resilientincharJ l acter whereby said prongs are adapted for l gripping said'pedestal and the socket for axial location thereon, a circularcushioning member adapted to be partially housed by said flange `andhaving a central open bottomed chamber, and means for Clamping thecushion member to the huh portion and including, a retaining platesentieri'A against the upper Wall of the chamber and secured to the hubportion of the socket.
